Abstract

A hermetic type scroll compressor includes a hermetically sealed compressor housing formed by first and second cup-shaped casings. A cylindrical housing portion is disposed between the first and second cup-shaped casings and has an annular inner block extending inwardly therefrom. The inner block divides the interior of the compressor into a first chamber in which the drive mechanism is housed and a second chamber in which the compression mechanism is housed. At one end, the drive shaft is supported by the inner block through bearings, and at the its other end, the drive shaft is supported by an annular projection extending from and integral with the second cup-shaped casing. Additionally, the stator is fixedly secured to the second cup-shaped casing. A gas passage, which allows the outer diameter of the compressor to be reduced, extends through the inner block to provide fluid communication between the first and second chambers.
